Local Road Research Board (LRRB) project number 889, titled, "Study of High Recycled Asphalt Pavement (RAP) Asphalt Mixtures was sponsored by the Minnesota Local Road Research Board. The project included: surveys of local road performance, study of asphalt activation in the plant and lab, and the design and testing of high-RAP laboratory ...

A LABORATORY STUDY OF RUBBER-ASPHALT MIXTURES FOR PAVEMENTS (With Supplementary Tests) j I I I I 'I L By L.A. Fickes Highway Research Project 46 D-14 Research Laboratory Testing and Research Division Report No. 163-a February 10, 1952

The ideal asphalt mixture has been studied, tested, and tried since the 1860s. As a result, asphalt mixture performance tests have also evolved. Since the 1990s, asphalt research has focused on binders, aggregate gradations and shapes, laboratory compactive effort, and the field performance of mixtures.

(amended in 2018) Section 501 Thin Asphalt Concrete Applications and Section 502 Asphalt Concrete Applications. The asphalt mixture types and applications are summarized in table 2. The Section . 501 of specifications applies to all asphalt concrete thin lift mixtures that are used as a finish course with a typical thickness of 0.75–1.5 inches.

Subsequently, asphalt mixtures with a basalt fiber content of 0.4% were prepared for further freeze-thaw tests. Through the comparative analysis of air voids, splitting strength, and indirect tensile stiffness modulus, it could be found that the performances of asphalt mixtures gradually declined with freeze-thaw cycles and basalt fiber had ...

asphalt mixtures to immediately address durability and raveling issues. The premature pavement failures across the state were the impetus behind the use of HWTT as a performance-related test to evaluate the rutting and moisture susceptibility of asphalt mixtures. Performance testing data

The objective of this investigation is to prepare the shape memory hydrogenated epoxy resin used for asphalt mixtures (SM-HEP-AM) and study its properties. The shape memory hydrogenated epoxy ...

The objective of this study is to investigate the moisture resistance of asphalt mixtures modified with liquid antistripping agents in …

Another study investigated the effect of both short-term aging and long-term aging on the dynamic modulus of ed warm mixture asphalt produced with different bituminous binders. It was concluded that the increase in dynamic modulus is affected by bituminous binder type, but aging was also a significant factor for all binder types [ 41 ].

Asphalt mixtures: Asphalt is a mix of sand, gravel, broken stones, soft materials, and asphalt. In Marshall's Standard Test * for designing asphalt mixtures, it was found that the percentage of asphalt required can be reduced as the density of the mixture increases. Therefore, adding cement bypass dust which has very fine and soft particles ...

Lignin and glass fiber were used as additives to improve the quality of road pavements and minimize moisture damage and cracking at low temperatures on asphalt pavement, according to a previous laboratory study. The aim of this paper is to make a significant contribution to the environmental assessment of the construction of road pavements using four types of asphalt mixtures based on the …

In another study, two different ranges of PET particle sizes (1.8–2.36 mm and 0.297–0.595 mm) were added to asphalt mixture as the modifier. The results indicated that MQ of both sizes increased as PET was added up to 4% by weight of the binder.

Asphalt mixture components and proportions are established and adjusted based on performance analysis with limited or no requirements for volumetric properties. Minimum requirements may be set for asphalt binder and aggregate properties. Once the asphalt mixture …

The influence of temperature on the shear performance of asphalt mixtures and the feasibility of using the deformation strength as an index of the high-temperature shear performance of these mixtures were explored in this study. Taking AC-13C and AC-20C asphalt mixtures as the research objects, uniaxial compression, rutting, deformation strength, and uniaxial static load creep …
